how to fix P0302 misfire code on my Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface, and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, gapping tool
• Remove the engine cover if applicable.
• Use a socket to remove the spark plug from cylinder 2.
• Inspect the spark plug for wear; replace if it shows signs of wear or damage.
• Gap the new spark plug according to the manufacturer specifications.
• Install the new spark plug and torque it to the recommended value (typically around 13-15 ft-lbs).

3. Inspect and Replace Ignition Coil

• Tools Required: Socket set, torque wrench
• Remove the ignition coil from cylinder 2 by unbolting it and disconnecting the electrical connector.
• Inspect the ignition coil for cracks or signs of burning.
• If faulty, install a new ignition coil by reversing the removal steps and torqueing bolts to the specified value.

4. Inspect Fuel Injector

• Tools Required: Injector puller tool (if necessary), cleaning kit
• Disconnect the fuel injector connector and remove the fuel injector from cylinder 2.
• Inspect the injector for clogs or damage.
• Clean the injector using a cleaning kit or replace it with a new one if damaged.
• Reinstall the injector and reconnect the electrical connector.

5. Check Compression

• Tools Required: Compression tester
• With the spark plug removed, insert the compression tester into cylinder 2.
• Crank the engine to get a reading. Compare the compression value with manufacturer specifications.
• If the compression is low, further investigation into valve seals or piston rings may be required.
